THTan (Nov 16, 2013):
Hi! I own a Samsung galaxy S4 which I bought in China two months ago. Can this card work in my phone? Thanks
robert (Nov 11, 2013):
Ken (Nov 12, 2013):
Check the expired date before you buy it. Normally it has a long time and can cover 3 months.
Izulica (Aug 27, 2013):

Is it possible to buy the 3g data package WITH voice services? I just wish for a sim card with big data bandwidth, but with the possibility to receive calls.

Ken (Aug 27, 2013):
There are such 3G sim cards however we have not. You may think of our 2G sim card which supports calls. Thanks.
Zi Ming (Aug 5, 2013):

I have 2 questions.

1) How long is the Sim card card valid for?

2) Is there 3G reception in the entire PU TIEN area?

Thanks. Hope to hear from you soon.
Ken (Aug 5, 2013):
It is valid for over 3 months. Is Pu Tien in Guangdong or Xinjiang?
Vivi (Jul 24, 2013):
Hi! I have purchased the china mobile prepaid card from 7-11 today and the calling and smsing functions work well. However, I cannot connect to the Internet and despite the confirmation of subscribing to the 200mb plan, I still can't surf the net. I am using an iPhone 4S. Please advise on how I could activate the data roaming functions because it didn't get activated automatically. Thanks.
Ken (Jul 24, 2013):
Please contact your seller, there are hundreds of plans in China and we do not know which one it is.
singh (Jul 18, 2013):

Kay C. (Jun 15, 2013):
Hi Ken, I have a Sim Card which is activated for use between May 20 to June 6 while in China. It says the Sim Card valid for 90 days since local set up. The sim card has another 1GB of data usage in balance when I left China. I am coming back to China again between July 6 to July 9. Is the sim card still active? Thank you
Ken (Jun 15, 2013):
Yes it is still active in July. Thank you.
sushan (Jun 11, 2013):
Hi Ken,
Thank you for your response. I have another question: If I use this sim card on one mobile device (ex. an iPad 3) first, can I later use the same sim on another mobile device (ex. an unlocked iPhone 4)? Do I need to call China Unicom to switch the sim card to another device? Thanks.
Ken (Jun 11, 2013):
Yes you can use this sim card on two devices and need not to contact China Unicom service to switch. Thank you.
sushan (Jun 6, 2013):
Will this sim card work with iPad 3 (Verizon version)? Also, does the $59.99 include the charge for sim card itself. This means that I do not need to return the sim card after I use up the data quote? Thanks.
Ken (Jun 6, 2013):
It works with iPad 3 however we are not sure if it
works with your Verizon version, please contact your
seller to check if your ipad 3 has limit or was
locked. This price include the sim card itself and
you need not to return it.
Fasi Ismail (Jun 4, 2013):
I have 300RMB=9G plan in china Unicom, how to do check balance period from english version?
Ken (Jun 5, 2013):
So you should have a local plan not roaming plan.
Mostly call China Unicom hotline or check at China
Unicom offical site is the easiest way, however
English service may not be provided in you location.
Logan (May 21, 2013):
Well this work on a unlocked Iphone 4?
Once I pay the ~$56 + shipping, I will not be charged any extra correct?
If I purchased today, but do not travel to China until late June will my 3GB began when I put the SIM Card into my phone when I get there?
Ken (May 21, 2013):
Yes. No any extra charge. It works when you come to
China in June. This sim card is only for 3G data,
voice calling closed.

Yes, it can only used for internet within China mainland. It can not work in Japan.
